UNITED STATES ROBERT F. SIMMGNS, OF CLEVELAND, OHIO.

ELEGTEIG I'TAIR VIAVER.

Application filed July 31, 1924.

To aZZ whom it may concern.

Be it known that 1, ROBERT P. SIMMONS, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful improvement in Electric Hair Wavers,of wh'ch the following is a full, clear, and exact description,reference being had to the accompanying drawings.

This invention relates generally to an electrically heated air wavingimplement and more particularly to certain improvements on the electrichair waver disclosed in my patent of April 1, 1924: No. 1,488,621.

The object of the present inventlon 18 to materially simplify theconstruction of the apparatus and correspondingly reduce the cost ofmanufacture 011 quantity production basis.

Another object of the invention is to so construct the apparatus thatthe proper degree of heat is obtained with the employment of a minimumamount of resistance element for producing the heat.

Other and further objects will appear as the description proceeds.

The invention consists broadly in providing a sinuous shaped metalliccasing with spaced heating elements arranged therein. The invention alsoconsists in certain details of construction and in the manner ofcombining or arranging the same all of which will be fully describedhereinafter and set forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is aperspective view of a hair waver constructed in accordance with myinvention, a portion of the outside plate being broken away in order todisclose the heating element between the wave forming heated plates;Fig. 2 is a transverse sectional view of the metallic casing with theheating elements arranged therein; Fig. 3 is a similar sectional Viewshowing a slightly modified form of easing; Fig. 4: is a detailperspective View showing one of the sinuous plates with the spacerarranged thereon and the heating wire coiled upon said spacer; Fig. 5 isa detail perspective View of the spacer removed; and Fig. 6 is a planview illustrating the manner of winding the resistance element.

In carrying out my invention 1 provide a sheet metal casing or envelopewhich is preferably made from two substantially similar wave-shapedmetallic sheets 6 and 7 re- Serial No. 729,218.

spectively which are placed together and united in any suitable manneralong their edges, said plates or at least one of them beingsufficiently upset or deformed to provide sufficient space between theplates to receive the heating elements and the spacer plate forpositioning the same properly within the metallic casing or envelope.The middle or crest portion of the wave-shaped plate 7 has a tubularstem 10 connected thereto which stem is provided with a handle 11 tofacilitate the manipulation of the hair waver. It will be understood,however, that the tubular stem can be connected to the plate 6 if sopreferred. The stem and handle are hollow to permit the connection tothe heating element 5 to be extended through the device to the flexibleexterior connection 12.

At a point 14 on the supporting stem 10 is a pivot 11 having prongs 16and 17 which pull the hair down into the crevices or the extremity ofthe looped portions of the waver, pressing the hair against the crest ormiddle portion of the plates and against the portions 18 and 19 of theplates 6.

The lever is manipulated by means of a handle 20 which is closed withreference to the handle 11 as indicated in dotted lines at 21 where thehair is forced down against the heated casing by means of the prongs 16and 17.

As thus far described, the features of construction are substantiallythe same as those disclosed in my patent previously referred to. In thatpatent, however, the heating element comprised the core having a heating wire thereon which core and heating wire was covered with suitableinsulation material and then the core, heating wire and insulatingmaterial were given a sinuous shape before insertion between the sinuousshaped metallic plates.

In my present invention, however, I propose to arrange the heatingelements in the outer side portions only of the casing. In order toprovide for the proper and expeditious arrangement of the heating wirein this spaced relation, I employ a spacer 28 which is arrangedcentrally of the plate 6 and has its oppositely curved edges extendingover the spaced bends in the plate and these 0ppositely curved edges areprovided with a plurality of tongues or books 28 upon which the loops orcoils 27 of the insulating heated wire are arranged. This heating wire27 is of the proper resistance quality to produce the proper heatingeffect and is covered with suitable insulation. The insulated heatingwir is thoroughly flexible and is looped or coiled back and forth asshown from one end of one side of the plate 6 to the opposite endthereof and it is then carried over to the opposite side and coiled orlooped or folded upon the opposite side member of this plate and it willof course be understood that the spacer 28 occupying the central portionhas the oppositely disposed hooks or tongues 28 upon both sidesor edgesfor the reception of the strands or loops thereon.

Where theinsulated wire 27 passes, from one side of the plate to theother, thereis a dead portion 27' which will carry the current but willnot heat to any appreciable extent, this dead member 27 being copper orother suitable conducting material. The heating wire 27 can beconnected, as pre viously described, at the points 5 to the wiresleading through the tubular handle 10 or if desired, portions of theinsulating wire itself can be carried partially through the tubularhandle but there is no necessity for extending the heating wire beyondthe points 5. By arranging the heating elements at the sides of thewave-like plate I have obtained an even distribution of the heat,inasmuch as the sides becoming heated convey or conduct the heatinwardly, and by properly proportioning the amount of wire in thespaced. heating elements, I am able to obtain a uniform heating of thewave-like plates.

It will of course be understood that instead of winding or coiling thewire 27 back and forth in vertical order as shown, it could, if sodesired, be carried back and forth in horizontal order by the properarrangement of the spacer, but in practice I have found the verticalarrangement particularly satisfactory and I am able to put into the,minimum space the. maximum amount of properlyinsulated heating wire.

After the insulated wire has been properly arranged uponfthe plate 6,the plate 7 is placed thereover and envelops the same. The edges of theplates 6 and 7 are united as previously described, and it will beunderstood that any other mod of connection could be employed andfurthermore the plates 6 and 7 could be so stamped that they could beheld together by frictional contact. Instead of making the plate 7similar to plate 6 in wave formation, it could extend straight acrossthe central portion, as most clearly shown in Fig. 3.

All of the other parts of the device, however, are constructed andarranged in exactiv the same manner as previously described. Thearrangement of my electric hair waver is such that the waver may bemoved over the difierent parts of the hair and a wavy sinuous shapedmetallic casing, and flexible.

heating elements contained in the outer members of said casing, andmeans forbringing the hair into contact with said casing.
